drivetrain ID

[mindthegap]

I just acquired a new to me 1966 Series IIA and have begun the process of a restoration. It was inoperable when I found it and was told by the PO that the transmission was seized and the engine hadn't been started in quite some time.

transmission and transfer case in the sickbay


I recognize as the 4th owner that some modifications have already been performed. The headlights are now on the wings, similar to a SIII and I've gathered that the engine has been swapped. Currently I have a Mitsubishi Fuso 4DR50 that I will concurrently be attempting to return to functioning status.

Seeing as not all parts are original, I can only assume to my naive eyes that any or all parts may have been transplanted, thus confounding my understanding of what I actually have.

What I'm wondering is if anyone here can recognize the transmission and transfer case by the picture....or point me to a location I can further ID this setup.

Any suggestions are welcome, thanks!

Welcome, and congrats! Check out www.lrfaq.org it has all of the engine/tranny id data.

the vehicle ID plate will yield some info as well...

Great looking truck, that cleaned up really nicely. Curious about the front grill if you could possibly post a photo of it. The gearbox is standard as fitted to these trucks though serial number is likley needed when ordering parts as slight changes were made during production.

Nice looking truck. Is that gearbox a spare or the only one you have? You're missing the intermediate gear cover, and probably the gear too. Probably the last owner took off an OD.
Mitzy diesels are good. Show us an under-bonnet picture.

Thanks everyone. I now know that it was originally a petrol vehicle by the chassis ID (no ID plate on bulkhead ) and am commensurately impressed with the conversion. That the diesel specific gauges are look stock and the subtle frame rework to accommodate the current engine, I was surprised to discover it's origins.

The gear box is original and very likely rebuildable (where is SerNo typically?). I have a bin of loose parts to compliment what's seen in the pic of gearbox-transfer case. I will attempt refurbishing that down the road but I do have another transmission option so I may not hang onto this one but for now it's the only one I have.

The transfer case is missing the drive gear and back cover where the Fairey OD sat; I also have the OD but no sign of gearbox gear/cover... use of the transmission as a functional unit will depend on acquiring those parts. The Fairey is in relatively good condition. The transfer case had no data plate but I found a casting number on the main case: HDA 539788. Hoping to find background on this tcase to assess how robust it is and what is the gearing. There are some downstream choices on axles that depend on it's viability.

Here's a photo of the engine bay, like spilled rice I continually find pine needles and debris after multiple cleanings.


The grill is not original as the headlamps were obviously relocated and I can see rework on the panels behind, like cutouts for the original headlamps. It consists of louvers which are currently seized although I intend to make every effort to return their functionality. There's an odd 3" cutout on the inside of the right wing, not sure if the wings derive from an SIII or if that was a feature on original SIIA wings.


The motor and starter were a package I discovered, as the solenoid is fouled up and upon removal I saw the mitzu symbol on the solenoid contact housing. That's being checked out at an electric shop tomorrow.

A manual pump primer! Very intrigued by this for ease of bleeding the fuel lines. There's also a hand lever throttle control as if originally purposed as an industrial pump needing to be flatline governed.

Wow--that 109 cleaned up well!

Transfer case gearing info located here on TeriAnn's site (chart labled "Series Transfer case Ratios" 1/2 way down the page).

Those adjustable rad louvers are awesome. Those are the first I've seen--Looks like a crude (or at least crudely-attached) version of ones that I designed last year but have yet to build. If you ever have them off, I'd love to see a pic of the backside.
